posterior separated by a narrow partition supporting in each cell 

 a desceudent, auatrapous ovule ^yitll micropyle looking outwards 

 and upwards.^ The fruit, generally accompanied by the persistent 

 calyx, is a loculicidal compressed capsule of varied form,- whose 

 descendent seeds generally contain under their coats an embryo 

 accompanied or not by a more or less abundant fleshy albumen. 

 The exostome presents an arillate excrescence entu-e or lobed. The 

 Milkworts (Fr. Laitiers) are shi'ubs, undershrubs or herbs. The 

 leaves are alternate, more rarely opposite or even verticillate, simple, 

 entire or nearly so and exstipulate. The flowers^ are in simple or 

 more rarely compound racemes or iu spikes sometimes short and 

 capituliform, sometimes few 'flowered. Each is inserted iu the axil 

 of a bract accompanied by two lateral bracteoles often articulate at 

 the base. 



In P. (liver sifoUa'^ and Pencea^ woody species fi'om the Antilles, 

 whose inflorescence is axillary, the lateral sepals are not much larger 

 than the others, and the exterior petals are a little more developed 

 than in other species of Polygala, for which reason they have been 

 made a genus under the name of BadieraS' To the ovary, supported 

 by a short foot, succeeds a fruit of which one cell is generally but 

 little developed.^ 



In certain species, of which the genus Chamcebuxns^ has been 

 made, the seeds have little or no albumen, and the cotyledons become 

 thick and plano-convex ; there is, as regards this, every transition
